Harry Potter's wizarding school revealed

Even though creator J.K. Rowling has completed her series of stories on the world's most famous wizard, the Harry Potter universe seems endless.

Her digital publishing company, Pottermore, offers content surrounding Harry Potter's fantasy world. It is now publishing three new e-books, a series called "Pottermore Presents," revealing facts surrounding the Hogwarts wizarding school. The short stories collections include several original texts by J.K. Rowling.

The three e-books of the series, made available not only in English, but also German, French, Italian, Japanese, Portuguese and Spanish, will be released on September 6 - cleverly marketed just in time for the beginning of the new term at Hogwarts.

The Harry Potter brand guarantees high sales

Rowling has celebrated another successful year. Last May, she was honored by the international writer's organization PEN.

Her play, "Harry Potter and the Cursed Child," opened to sold-out crowds in July. The script of the play offers an eighth part of the Potter series and shows the life of the wizard as an adult who sends his own son to Hogwarts. It reached record sales in the UK, the US, Canada, Germany and is still at the top of international bestseller lists.

And finally, the prequel to the Harry Potter series, "Fantastic Beasts and Where To Find Them," will hit theaters in November. Rowling wrote the script to the movie.
